How changes in river geometry impact flood hazard in BrazilNARA Subscribed
The Cerrado biome, spanning ~2 million km 2 , is one of the most extensive and biodiverse tropical savannas, yet it is paradoxically dominated by only 30 hyperdominant tree species (~2% of all species, > 50% of all stems). However, their vulnerability to climate change and the effectiveness of current conservation efforts remain uncertain. By combining (i) species distribution models calibrated with edaphic‐climatic predictors...
Are Biological Responses Consistent With Ocean Warming Across Levels of Organisation in the Bay of Biscay?NARA Subscribed
Global change has altered the climate and biogeochemistry of oceans, which has cascading consequences across all levels of biological organisation. Under warmer conditions, most fish species develop faster during early life stages but reach smaller adult sizes. At the population level, fish respond to warming by altering the phenology of key events and/or shifting spatial distribution. The interwoven action of these responses...
Specific myogenic microRNAs termed “myomiRNAs” are involved in skeletal muscle development and regeneration, and an obesogenic environment in utero may affect these processes. The present study aimed to determine whether this environment induced variations in the expression levels of myomiRs-31, −133, −136, −206, and −296 and whether the administration of (-)-epicatechin (Epi), an exercise mimetic, could modify these variation...
Admixture With Cultivated Sunflower Likely Facilitated Establishment and Spread of Wild Sunflower ( Helianthus annuus ) in ArgentinaNARA Subscribed
A better understanding of the genetic and ecological factors underlying successful invasions is critical to mitigate the negative impacts of invasive species. Here, we study the invasion history of Helianthus annuus populations from Argentina, with particular emphasis on the role of post‐introduction admixture with cultivated sunflower (also H. annuus ) and climate adaptation driven by large haploblocks. We conducted genotypin...
Compensation versus deterioration across functional networks in amnestic mild cognitive impairment subtypesNARA Subscribed
Functional connectivity studies to detect neurophysiological correlates of amnestic mild cognitive impairment (aMCI), a prodromal stage of Alzheimer’s disease, have generated contradictory results in terms of compensation and deterioration, as most of the studies did not distinguish between the different aMCI subtypes: single-domain aMCI (sd-aMCI) and multiple-domain aMCI (md-aMCI). The present study aimed to characterize the...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
Fish possess lipases from embryonic development to adulthood. Lipase activity methods vary and significantly differ in terms of the concentration of the substrate used, bile salt, Ca2+, temperature, pH, and type of lipase units, which limits comparative studies. The three most-used substrates are p-nitrophenyl (p-NP), β-naphthyl (β-N) derivates, and emulsified natural oils. These were selected to be redesigned in this study to...
Aim To determine the relationships between the functional trait composition of forest communities and environmental gradients across scales and biomes and the role of species relative abundances in these relationships. Location Global. Time period Recent. Major taxa studied Trees. Methods We integrated species abundance records from worldwide forest inventories and associated functional traits (wood density, specific leaf area...
